I have a 3-yr. old Great Dane, since he was 8 weeks old. He is exceptional in every way, gentle, smart, well-trained, never had one accident in the house and is more civilized than a lot of people I know. And yes, he has been neutered. He is beautiful, weighs 192#, and is confident and very affectionate. About 1 yr. ago, the neighbors behind us added a small female rat terrier to their other two dogs (had one male and one female mixed breed dogs that were never a problem) - and my perfectly comfortable
life with my dog became ridiculous. The terrier is a female, I don't know if she is spayed. I have a great yard for my dog, grass, trees, running room, and even other dogs for him to play with almost daily.
BUT, all he has to do is hear that one dog bark, and he charges the fence at
the spot where the dog is (it's a 6 ft. redwood fence, with a sharp drop on
the neighbors' side, which the terrier scales to come bark at my yard). His hackles are up, the growling is loud, and he paws at the fence so hard that
he has broken a toe (to the tune of $910.00), cut his foot twice, and scraped
the fence. I have since put up a separation in the yard and only let him out
there when I can watch. If the terrier isn't out there, he is perfectly content and enjoys playing and rolling around in the grass; but all it takes is one yip from it, and it's all over. I call him away from the fence, and close the area
off. He stands in the other part of the yard, and talks to me (like he's trying
to tell me he had to do it or something). You've probably heard Danes talk, they really are almost human in that way. I've tried repellents, natural and other, on both sides of the fence - nothing. The neighbors apparently are
not interested in keeping their dog off the hillside (can't blame them, not
their problem) - so what am I missing? help... Thank you
